Its hillside vineyard is divided into numerous small blocks, allowing each variety and clone to be matched carefully with the estate’s distinctive soils and exposures. Caliza Winery

Jack Creek Cellars is a small family-owned vineyard situated in one of the coolest sections of the Willow Creek District. Modest yields and careful farming allow the family to produce limited quantities of Pinot Noir, Chardonnay, Grenache, and Syrah. The winery is particularly notable for demonstrating that the district’s cooler pockets can produce refined Pinot Noir and Chardonnay alongside traditional Paso Robles Rhône varieties.
